switch-buffer-functions
Hook run when switching current buffer
What is This?
This is a Emacs Lisp package that provides a hook variable
switch-buffer-functions.
This hook will be run when the current buffer has been changed after each
interactive command, i.e. when post-command-hook is called.
When functions are added to the hook, they will be called with the previous buffer and the current buffer. For example, if you eval:
(add-hook 'switch-buffer-functions
(lambda (prev curr)
(cl-assert (eq curr (current-buffer))) ;; Always t
(message "%S -> %S" prev curr)))then the message like "#<buffer *Messages*> → #<buffer init.el<.emacs.d>>"
will be displayed to the echo area each time when you switch the current
buffer.
